consrnocriom Application filed December 3, 1918. serial Ito. 804,501.

To all whom it may concern:

Be it known that I, Fnnonrcn J. Form, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have'invented new and useful seats and like constructions wherein the k springs are covered by upholstering- The principal object of the invention is to provide a simple and eflicient device wherein the springs may beconneeted eonveniently without rivets or other similar securing means to theframe, wherein the frame is adapted to receive suitable up-' holstery tacks and wherein the springs are properly connected together without tying.

Another object of the invention is toconstruct the frame strip in'such a manner that the springs niay be connected thereto without using rivets or other similar fastening devices and also in producing a strip with an insert arranged to receive upholstery fastening devices.

Further objects of the invention will appear as the following description is read m connection with the accompanying drawing, which forms a part of this application, and in which- Figure 1 is a bottom planview showing a portion of aspring cushion seat frame. Fig. 2 is a detail top plan view showing the manner of connecting the springs. Fig. 3 is a perspective view of one of the spring connecting clips. Fig. 4 is a transverse section through the spring frame showing what may be termed the upholstery strip on an enlarged scale.

- The cushion comprises the frame 1, supporting wires 2 extending across the same and having mounted thereon the coil springs 3 which are connected to ther by the clips 4 and an up or retaining ame 5 'of resilient material. he frame 1 1s constructed of one or more pieces of material, preferably sheet metal of the required strength and each piece is bent, as shown in Fig. 4, to produce opposite pairs of parallel flan cs6 and 7, the flanges-6 being double and aving a relatively narrow space between the same while the flanges 7 are of single thickness and having a. relatively wide space between the same. springs are attached to the frame 1 by inserting portions thereof into or between the flanges 6 and upsetting or offsetting one of the flanges so as-to'clinch the wires therein. Seated within or between the flanges 7 is a strip of wood or other suitable material indicated-at 8. This strip is held in -position between the flanges by the burrs 9 formed b% pinchin holes in the metal, as shown. he upholstery for covering the springs canbe readil tacked to the strip 8 without weakening the frame piece and as these fasten-ings are the onl kind used in the construction of the cus ion it will be readily seen that the same may be constructedin an efiicient and relatively cheap man ner, at the same time producing an extremely light construction.

What is claimed is Ina spring cushion, a frame comprising a single strip of sheet metal bent at its opposite ends to provide a pair of parallel flanges, and bent at its intermediate portion and in an opposite direction to the-first mentioned flan to provide another pair of converging I an es the latter mentioned ouble thickness, springs flanges being of and supporting devices secured between the double thickened intermediate flanges, an upholstery mounting arranged between said end flanges and i in said strip for holding the latter therebetween.

Intestimony whereof I aflix my-signature in presence of two witnesses. FREDRICK J. FOILL. Witnesses:
